I have NUC7i5DNBE board (BIOS v59), everything works fine until i accidentally selected Devices->Video->Basic Flat Panel Configuration->IGD Flat Panel->Disable and saved it.
Since this moment any Flat Panel Configuration tab options magically disappears regardless Display Port adapter (iEI DP-LVDS-R10) connected or not. DP adapter has stopped working with this NUC.
I checked another brand new NUC7i5DNBE board (BIOS v40) and i can see Flat Panel configuration option regardless DP adapter physically connected or not. Of course i didn't try to save Flat Panel "Disable" option.
What i tried to see Flat Panel Configuration again:
1) Load BIOS defaults (F9 ->Save)
2) Reset ME configuration using MEBX reset header.
3) Downgrade BIOS to V58 (can't downgrade to v40 because it says incorrect BIOS version)
Flat Panel Configuration Tab still empty.
Could you please advice how can i restore Flat Panel configuration and get DP adapter working with this board?
Downgraded to BIOS v55 and Basic Flat Panel Configuration options magically appears, uhhh.... Spent a few hours fighting this.
Anybody who saved "Disable" flat panel will never see his Display Port until downgrading to correct BIOS version for this board.
Happy to find solution, would like to ask support for fixing this magic.
Thank you for your reply.
I agree that IGD Primary video port works as expected
But i have no idea why eDP option wil be hidden with no way to unhide it back.
It works as one-way ticket.
If you select "Disable" you have no way to switch Display Port back to "Enable".
I guess It looks like bug.
